Convert Apple ProRes to lossless Windows Codec?
I have a Pro Res 422 encoded QT file that I need to send for further editing on a Windows machine. The recipient said he can't take Pro Res files as he lacks a Mac. Is there a lossless intermediate codec I could convert to on a Mac system? The best I found on Final Cut was to convert to AVI in DVCPRO50 (the footage is digitalized SD), but I would still rather have no downgrade in quality. On Premiere I have DNXhd, MXF HD, etc. but no Huffyuv or Lagarith as I only have a Mac.
Is all this trouble worth it? I thought one could edit Pro Res on Windows if Quicktime was installed? |
open your Prores file in TmpgEnc Mastering Works 5 and output to avi, choose Canopus HQX Super Fine, this is 10bit and you will not get banding
Post 10 of Anton Strauss http://forum.grassvalley.com/forum/s...ad.php?t=24983 or Video to Video converter: http://www.videotovideo.org/ Give me a small section of the ProRes 4:2:2 MOV, I try that on a PC. ProRes is a standard feature on Apple Mac computers, whereas with Windows PC's QuickTime component (media player) must be installed in order to play and edit a ProRes file. |

Thanks for the help...I could not download TmpgEnc as it was not free. I was trying to see how I could convert to a viable format using only a Mac, but did get a chance to use Video to Video on a PC. I converted it to an MPEG-4 file in xvid, but is that suitable for editing? The file size was much less so I do not know if image quality suffered. I may just export Pro Res in an avi container...

Yes, unfortunately, these programmes cost dollar or euro or Swiss franc however, it must not always be the newest version. here I can encode your movie in VirtualDub to Lagarith 4: 2:. 2 Ie But Directly in Edius under Windows 7 32 bits without problems read in. Picture 1 = Original Picture 2 = VirtualDub Picture 3 = to VirtualDub Picture 4 = original ProRes and result in Edius [V.6.08] |
Thank you, can a normal PC without VirtualDub or Avidemux read Huffyuv or Lagarith? When I converted Pro Res to AVI Huffyuv the Adobe Premiere on my Mac could not read.

Adobe premiere CS6 can recognise here the original and also the Lagarith version.
Huffyuv_MT [HYMT], however, not. See picture |
What if one only has a Mac? I have options like to be DVCPRO50, DVCPRO HD (but it would later have to be cropped), MPEG IMX/ XDCAM, or Apple PNG.

Mac I do not have.
DVCPRO50, DVCPRO HD, MPEG IMX/XDCAM.... and other under Edius Apple PNG. and other with Procoder 3 or Sorenson Squeeze 10 and still other also go under Windows PC. With avisynth it does not work on a Mac. FFV1 cannot be read in 4:4:4 on a Mac. |
Thanks, what I meant is that Mac is a bit limited in conversion options, and those are the codecs I have that appear to be the best of them. Would you recommend any of them (assuming I can not access a PC for transcoding)?

Professional workflows should have access to ProRes without any issue. To convert formats, I often use MPEG Streamclip (Mac version required) and export it to uncompressed AVI. From there, stick it on a Windows machine, and do whatever you want.
Avisynth and VirtualDub, I think, have a way of opening ProRes422. But I prefer the Mac-native method. What are you having done to the file? Did you ever solve that dropout issue? I never heard back. Because of your sample, I perfected the process even more. |
Thanks. I think I did give you an update but given how busy you get I thought it was understandable. I believe the person just does not know if Pro Res works on Windows, when it does. Problem is, when I send it to for post-processing (hint hint) he would not be able to export as Pro Res.
I just received that tape from the first place, but because of their TBC, they were only able to fix about 85% of the dropouts, leaving dropped frames in areas. I don't want to send it to you until the conversion occurs with no dropped frames (it's a U-Matic). You said the issues could possibly be reduced if a better TBC was used, like DataVideo. The next person I tried to find to do this said that only a U-Matic TBC with a digital dropout compensator could improve this by replacing dropout lines as they occur. It would take the RF from the VTR when the signal was low. Alas, he only has built-in compensators on other VTRs, since U-Matic is quite old. Is that what you were getting at? Another place said it usually handles tapes that other companies had trouble with, but their set-up is an ADVC-300, which from what I recall is not the most professional option... |
If a Canopus ADVc300 is there would already try ichs.
In front with S. video and audio purely. Behind by YUV [Y Cb Cr] out. All Settings on Default. The ADVC is no professional device, however, I already succeeded sometimes. |
I'd only worry about dropped frames, and not the dropouts. The magnetic dropouts can be fixed, as you saw. Dropped frames, however, cannot.
I call BS on this: "only a U-Matic TBC with a digital dropout compensator could improve this" - If referring to the dropouts, his skills are just limited. - If referring to dropped frames, I still say to try a DataVideo TBC (100, 1000, 3000, etc) The ADVC-300 is wrose than the 100/110 because of the artifacts it creates when trying to "filter" the video. Remember, that's the best that existed about 15 years ago, and it's hardware on that devices that cannot be shut off. So it is forever crappy. I often doubt this as well: "it usually handles tapes that other companies had trouble with". I'd have to see proof of that. |
Thanks.I too don't care about dropouts, only dropped frames. But the first place had trouble even keeping the image aligned, leading to the frame drops. That is why I am concerned about the second company if they are using such old equipment. With an ADVC 300 I might as well do it myself as Goldwingfahrer wrote.
The other guy (who is seems to be experienced in this), has a GTH ACE and a G2 MSTC Ultima. Could either solve the issue without resorting to a Datavideo? I showed him the critique of the GTH ACE here on this site and here is what he said: Quote:
