Huffyuv workflow for editing
Hello,
Now that my setting are optimals (I think so) to generate huffyuv file. My first goal was to generate stables lossless file for archiving. :congrats: ======= Now I would like to know what is the ideal workflow 1) burn directly a DVD? this week-end I did it with a 2 pass MPEG-2 compression with avidemux on a 18.5 GB file (42min) That way I burn a ~1.3GB DVD. Its pretty straight forward but I will like to know if there is things that I should be carefull with for this simple task. 2) if I want to do some editing I read that ideal worflow may avoid too many color space conversion. What are you doing when you have to work with YUY2 file? I read that AVISynth may offer some filtering option in YUV. Is it THE tool for this kind of file? Quote:
It seem that from what I can understand :hmm: Premiere can work now not only in RGB!? On a other hand I think I cannot work huffyuvfile on CS5.5 http://forums.adobe.com/message/2891276#2891276 My choice seem to be use a 1) other program with huffyuv or use codec like Lagarith and UT that can still be use for archiving and that seem to have no problem with 64bits cs5.5 (assuming that CS5.5 can work in YUV color space) Well I will like to know what you're doing when working with huffyuv files to avoid weaky link in the chain. Many thanks again |
Okay
Concerning Audio I extracted raw audio via Virtualdub. Denoise it in Audacity. Then I tried to load the denoise audio file in VirtualDub. I succed but "I think" that I cannot avoid the RGB conversion process of the video? I ended with a way too big file. Instead I tried to incorporate my denoise audio file during the MPEG-2 encoding with avidemux. It work! Basically it mean that I cannot archives my YUY2 file with the denoise WAV file from audacity? Thanks again.:D |
Method to encode seems fine, Avidemux 1.3GB ~42min, assuming 352x480
Try to avoid colorspace conversion, yes. But also don't beat yourself up if you have to do 1-2 conversions. Avisynth is fine. There's not much loss between YUV/YUY2 and RGB32. Use Avisynth to convert the colorspace. That helps. You want to avoid it, but within reason. Obviously Adobe Premiere is worth an RGB32 conversion. Denoise audio in something else. Audacity is freeware, and is useful. Sound Forge is nice, and payware. Sometimes you have to archive audio edits separate from video. I think that answers you. :) |

http://forums.adobe.com/message/2891276#2891276 One option may to use Avisynth or Virtualdub to convert in RGB and then open the file in Adobe premiere. But now knowing that there is a bunch of video filters (assuming that they are equivalent to Adobe) in Avisynth and Virtualdub and that I can handle Audio with Audacity and compress with Avidemux, do I really need Adobe premiere:D with all his fancy complements (encore, media encoder) Quote:

BIG THANKS |
Audio is stored in a separate stream in AVI files, you can edit it independently of the video. Your HuffYUV problems may be because you only have the 32-bit version of the codec installed. Premiere Pro CS5.5 likely requires the 64-bit version in order to properly decode the video. Premiere Pro can natively handle YUV format video, so color space conversion should NOT be an issue.
There are a few tools to integrate Premiere into your workflow. The AviSynth Import plug-in: This allows you to import any AviSynth script directly into your Premiere projects as if it was a standard media file. You can use AviSynth this way to avoid having to re-save your HuffYUV footage in other formats before importing. 32-bit: http://valion.net/csavs/ 64-bit: http://pwolfamv.com/programs/csavs64/ (requires 64-bit build of avisynth and avisynth plug-ins) DebugMode Frameserver: This tool is a godsend in my workflow. It allows you to feed your finished Premiere projects directly into an Avisynth script and/or video compressor without first saving your finished project to a video file. You avoid a generation of needless compression and save some hard drive space. I use it to feed my Premiere projects directly into AVANTI, which is a FFMpeg front end with AviSynth support. http://www.debugmode.com/frameserver/ |
Hi NJRoadfan :)

Sure I tried with the 64 bits version! Right now when I do a G-spot check on my AVI YUV2 file I got a "codec status indeterminated" + unable to open it in CS5.5. Well I got the same problem as some others users reported in adobe forum discussions. Which methods have you used to install it? Quote:
You can be sure that if I am able to install the codec in CS5.5 I will have a look on the advices you gave me above. |
What is the FourCC of the video files? HuffYUV files are identified as HFYU. If you captured with the Multi-threaded HuffYUV, their FourCC is HYMT and they are incompatible with the original version of the codec. To complicate things, FFMpeg's HuffYUV compressor tags files with a FourCC of FFVH. Post your GSpot output, I'm curious what it is IDing these files as.

Now what you see is the G-spot for the original file generated that have been open on a other computer (newer) that I want to use for editing. Sure I tried to install the 64bits codecs because it's a 64 bits W7 with 64 bits CS5.5. So what you will see is HFYU!? |
It looks like the 32-bit HuffYUV codec isn't installed at all. You have a codec issue here, the files likely will not show video if you open them in VirtualDub or Windows Media Player. VLC is the exception since it uses its own built in decoders. Installing both the 32-bit and 64-bit versions of VirtualDub is a good way to see what codecs are installed for which platform type.
I just tested importing a HuffYUV AVI into Premiere CS4 and it worked fine, so the problem is not with Premiere. |
Good morning,

Hi NJRoadfan,
Okay I did succed to install the huffyuv 32bits codec on my personal computer and then I was able to play avi file in windows media players on a Windows7 64bits. Also I can see the codec in virtualdub. I did succed with the Dos installation method otherwise nothing work. ============== When you are talking about being able to use huffyuv files in your premiere CS4 is it 64bits? What is your set-up? Because now I don't wanna make mistake in the installation process on my working computer. I have CS5.5 64bits. So I should install a huffyuv 1.9.11? even if they suggest to use the 32bits version unless necessary and not the 1.9.8 version with all the filters avalaible here. For the codecs I should use the 64bits codecs of huffyuv also available here? Thanks |
Hate to get off topic, but just wanted to say make sure that you use 352x480 otherwise 720x480 may come out looking blocky at that bitrate.

I didn't remember why but then I read in the guide "understanding your source" So I guess this is why right now that my video are 640x480 Quote:
Me I want to have 1)best archives possible and 2)editing possibility THANKS |
Quote:
Just forgot to mention that despite Windows Media Player been able to play the file on my personal computer, G-spot still say "codec status indeterminated"? |
I wrote that.
Edit as 720x480 or 640x480. These days, 720x480 is probably the better choice. Final MPEG export is 352x480. So there you go. :) |
Quote:
Acquire and edit at 720x576 Final MGEP export is 352x576 |
For PAL, use 720x576.
Final MPEG export is 352x576. |
Hello HJRoadfan,
I finally suceed to install the 64bits huffyuv codecs but I have use a twist that I am not sure to understand myself:D First I was not able to install the 64bits with the Dos procedure. But I was able to install the 32bits codec with the Dos procedure. After trying many things... I finally extract the 64bits codecs in the "programs files (x86)" folder instead of directly on the c: Right click on the "huffyuv.inf" and install. Do you want to overwrite the file (the 32bits codecs was already installed), "yes". There we go, now I can open AVI files in premiere CS5.5 Next step, try to install the plug-in that you mentionned earlier. Thanks |

Okay I did install Avisynth 64-bit I followed this thread Installing 2.5.8 32 bits and installing the 64-bit dll after. I also installed virtualdub 64-bit. Quote:
Now if I unterstand well, Avanti should be installed with FFMeg. Avanti is 32-bit (and there is some notifications to install it in Windows7) and FFmeg is available in 32 or 64 bit. Wich FFmeg should I install? Right now you are talking to a guy who actually never use avisynth and all this new plug-in. So right now I really don't know if my installation is ok. I guess you can indicate some kind of test or for what should I look when I open CS5.5 or Virtualdub. Thanks |
