Hi to all,
I have noticed, that the FFV1 encoder configuration window doesn’t show all possible settings for this codec. You can actually also define an interframe compression by using the GOP argument of ffmpeg: https://trac.ffmpeg.org/wiki/Encode/FFV1 Why Golomb Rice coding could just be applied to 8Bit Video? |

Hi, to set GOP argument you can use VirtualDub`s "Force keyframes every ... frames" option. It also overrides maximum gop for x264, x265 etc.

I already experimented with it and the good news flac is supported in wav/avi formats. The main difficulty is VirtualDub's AVI interleaving algorithm (there was something missing in it). |

But VDubFilterMod does not only save AVI. It can also save more modern and flexible containers. — Now I wonder whether it is possible to restrict the content format selection to output containers.

I'm thinking about this. It is possible (not easy) to find which formats are compatible. Making the UI right is more difficult. There should be single "compression dialog" with file format, video and audio.

Is there any particular reason why the default output container is still .AVI. Could it not be say, .MKV?

Should not be changed unless user sets some preference, default should always be AVI.

The AVI container is so last millennium. It should have been phased out years ago.

There is long list of very legacy features. Who will benefit from this changed default? Things which do not work in MKV now: Uncompressed video: not tested at all. Audio offset: not applied (maybe will fix soon). File comments: maybe not important at all. Also, technically you can delete any plugin and live without it. And since MKV output is in the plugin, how can it be the default?

AVI is still alive and it is supported and used, also for archiving. Quote:
I saw it also at this year’s IASA conference and that is the reason why I am here, because I consider it as a possible solution beside IMF for our archive. So, it also would be ideal if there could be a menu inside VirtualDub to edit the metadata of the mkv header (aspect ratio, cropping etc.) |

VDubFilterMod has already come a long way since Avery Lee's original VirtualDub, easily passed VirtualDubMod; and its possible future sounds promising with such an inspiration.

Well, i'm still using a lot AVI, because in my video processing, i have several steps, and i save each steps in lossless avi file (UT Video actualy), which is the easiest way. And it's the final AVI lossless file i feed to my encoder at the end. I absolutely don't want AVI to die, as said, each format as its benefit.

Today have tried to load 6K DPX files (roughly 205MB per file) in VirtualDub.
And it could open the sequence, even 16Bit per channel and with alpha. Seeking failed (that could also be a problem of the low access speed of the workstation). But as I tried to encode it, VirtualDub crashed because it could’t allocate enough memory (for one frame I guess). I have tried to lower the resolution per resize and the encoding started, but it also ran out of memory after a few frames. Last edited by AKBabel; 6th December 2017 at 18:27. |

I experimented with 5000*2500@rgb48 converting to FFV1, and it used around 2GB for encoding. Are you trying with 32-bit version?
