Missing step(s) between capture and encoding?
1 Attachment(s)
Hello Guys,
finally i could capture VHS tapes into lossless format
Now i understand why we need to encode it into final / delivery format. The file size is huge and VLC could only playback the footage after i installed the HuffYUV_mt.inf codec. I didn't want to complicate the process with editing, corrections, etc. (it did'nt need it) just produce an output to playback in VLC without other codecs, consuming less storage. I choosed AviDemux based on thread suggestions but after i open the captured file the playback screen is green, Video Decoder is ????, the version is 2.6.4 and i don't know how to proceed? :depressed: Attachment 15813 I missed a step? Actually these two apps (Avidemux and VirtualDub) are good and enough for these process or should i choose or add another one? Maybe the capture rig with XP SP2 is not optimal for Avidemux? Thank you. |
It was never meant to playback the lossless files, The reason to capture lossless is to overcome the losses associated with de-interlacing, applying filters and encoding.

Sorry i was misunderstandable. I know that lossless is not for playback. This is my personal experience so i understood really well why it has different purpose. The question is why Avidemux cannot handle lossless format. Do i need something to do in VirtualDub or in any other application, maybe just my Avidemux is not working (version or driver issue) or something else.

I don't use Avidemux but you can post a short sample here so other members can check the parameters of the video file.

AVIDemux current version is 2.8.1.

I installed the latest 32 bit Avidemux version 2.7.7. Still not working but at least i got some error messages:
Attachment 15817 Attachment 15818 Maybe some Microsoft Visual C++ Runtime Library missing? Here is the sample file: Attachment 15820 I opened it in VirtualDub where i previously captured in lossless format with HuffYUV codec, selected a short footage from the original capturing and selected Save as AVI... menu item from File. Maybe this is not right way to get samples, right? AviDemux is also craching with this footage. Finally i gave it to GSpot for getting some more information that could help: Attachment 15819 |

I think the issue is the Multithreaded HUFF codec; my AVIDemux 64bit 281 won't open it either.
Handbrake will open your AVI and you can recode it to MP4. If you want to edit your AVI (trim the ends off, for example), you can do this in Virtual Dub using the trim buttons at the bottom, then encode it with x264 into MP4 format. Let us know if you get stuck. Lollo, you need to calm down and stop bashing everybody. Quote:
Now whether that was the correct thing to do does not warrant your rant. Did they go against what you had told them? No. So don't be so critical. A (possible) mistake was made with the capture codec selection; work with them, not tear strips off them and virtually accuse them of being an idiot. Quote:

you did not do in your first replies. Who is ranting? Quote:
the original HuffYUV codec. Quote:
in VLC without other codecs" I have understood that he did not want an additional codec, like h264 (but I may be wrong). Then the only way is to use the original capture codec, but it cannot be HuffYUV_MT. If he wants to save space, then the h264 compression is absolutely adequate. Quote:

Thank you for replies guys. We can agree that HuffYUV_multithreaded codec is not reliable, not working therefore not suggested. I am just wondering then why is it listed among the other HuffYUV codecs
Attachment 15826 when everything that considered as junk eliminated from this forum. Maybe no one uses it, just people like me. So i suppose i have to start all over again the capturing with the original HuffYUV codec. I am unsure so please confirm it to me that the first step in the process is to capture the tape with VirtualDub or ATI MMC with less functionality (i know and used these two only), with lossless codec without any compression to get the best possible quality from the tape?

Cortez, you're speaking my language! :)
A few points: So i suppose i have to start all over again the capturing with the original HuffYUV codec. I don't think so, but I seek confirmation from the floor that the following procedure will not degrade your video by re-encoding it. It is easy to change codec in VDub: Open the file Video>Fast Recompress Video>Compression>set normal HUFFYUV. File>Save video. So VirtualDub can also encode the lossless format into MP4 wow. I didn't know that VirtualDub is capable of that. I use Virtual Dub 2 because it has the x264 encoder in it already, although you can "install" the x264 codec so it can be used by earlier versions of VDub and other programs. You use a similar procedure to that above, except you choose Video>Full Processing Mode. I still don't know the meaning of the jargons like encode, demux, transcode, lossless, MP4 formats/containers as you can see. Therefore i don't know what should i do with the existing footage using what application that is suggested. If you are happy with it as it is ie no more editing required (you do know you can do all sorts of improvement to it using Video>Filters :eek::eek:) then you can just export what you already have straight out of VDub into MP4 (the file container) using the x264 video codec. You'll then be able to view it on/with anything; TVs, tablets, phones, computer. And I agree, Handbrake is a weird name! |
Thank you very much Hushpower you are very kind. Actually i don't speak your language very well because english is not my native language as you can see, using the same words and phrases which i know, i am sometimes misunderstandable but it seems you understand me very well. :laugh:
I gave back the VHS tape a long time ago so i have to try it reencode to get mainstream x264 MP4 format. If it doesn't help i will ask that tape again. Quote:
Okay first i try to reencode the lossless file with VirtualDub using x264 encoder to get a MP4 file. Where can i find x264 codec to install it? I suppose the installing procedure is the same as by HuffYUV_mt, right? If VLC still cannot play this result then i have to return to the last "checkpoint" reinstall VirtualDub with the normal HuffYUV codec and start with an other test tape. One more question. How can i call these video files during capturing process with the appropriate technical jargon? I know footage, video, video file, raw material. |
Cortez, your English is great! Certainly a whole lot better than my... :D I'm sorry about my earlier exclamation :You're speaking my language!". It probably sounded offensive but was meant as a compliment and that we were "on the same page/thinking alike".

https://www.videohelp.com/software/VirtualDub2 I know it seems silly to have two VDubs, but they don't "install" as such, so they don't mess up your system. VDub 2 is not the best for capturing, according to The Lord, but it is more modern than VDub 1.9.11, can open all sorts of files, and has the x264 encoder built-in. I did have trouble with the external x264 encoder in 1.9.11 so now I just use VDub 2's internal encoder. Quote:

Export MP4 with Virtual Dub 2 Open file Video>Full Processing Mode Video>Compression: choose x264 8 bit, then on the Configure button: set Rate Factor to 16 (that will be good quality, the lower the RF, the higher the quality but the higher the file size) OK out of those screens Audio>Full Processing Mode Audio>Compression: choose FFMpeg AAC, click Configure and set bitrate to 192kbps (good quality audio) OK out of those screens Ready to roll! File>Save Video... On the Save Video screen: Set the Save As Type to MP4 Faststart (I think this means the file will quick-start playback when it is being streamed eg on Whatsapp). This "type' is hte container we talk about. AVI, MOV, VOB, MKV, MP4 are all containers. Insert an appropriate file name Note: at the bottom are the details of the video and audio codecs. I often forget the audio and it will be on PCM and then I'll get a message when I try to save that "you can't do that!" (that is, PCM audio in MP4 container). Then I go to Audio and set it as above. Hit Save you will soon have a H264-codec MP4. Stick them on a USB and play on your TV, or through your local network. I'm no expert with this, so there will probably be others who correct me on these settings. Handbrake is also fairly easy to use, but Vdub has good, easy-to-use filters such as Colour Mill, which is terrific for colour and Brightness/Contrast correction. There are also filters for De-interlacing (not quite as good as AVISynth but much easier). As I mentioned earlier, the elephant in the room is headswitching noise and the ragged side edges. I don't understand how to get rid of those using VDub or Handbrake. Give all that a shot. If nothing else, it'll improve your understanding of it all, even if you do end up using something else. |

Thank you for the detailed tutorial how to encode my video to delivery format. I have to try it soon. |

I followed your instructions and here is compressed file: Attachment 15874 Hurray :congrats:. Thank you for your help. Now the question is the quality again. In the first phase after the lossless capturing it is called "correction"? Here i have also a head switching noise. I reduced it to this size by misaligned the roller in the VCR that is forbidden, otherwise it would fill the bottom quarter image. For encoding it's just adjusting sliders from bad to good quality? |
