Im trying to combine and compress 60 avi files from a DVI capture that were from a single day.
I tried using Avidemux to combine, which works fine, but when I compress using hevc, either into an avi or an mkv container, my media player no longer automatically deinterlaces (maybe the video is no longer 480i or something is happening in the compression process). I tried with ffmpeg in virtual dub but the same thing happened (media player classic no longer auto-deinterlaces the video).
How can I combine batches of avi files into one, while compressing as much as I can without significantly impacting naked-eye quality, and have the file automatically deinterlaced by media players the way they are right from DVI extract?
Open to other programs.
Thanks for your help!

Did you encode interlaced ?
For avidemux -
Push configure > frame tab > checkmark interlaced, bottom field first (DV is BFF by convention)
Also, AVC in MP4 container (instead of AVI container) will probably be supported by more software and hardware players
Also, don't for get to set the aspect ratio ( native DV is never "square pixel") . It's in the output1 tab in the configuration
I did not encode interlaced. trying that now. Is there an automated way of setting a chapter for each file segment I combined (with the file name?) Would be nice to keep the original time stamps.
Thanks so much for your help!!! Have spent many hours on this (I thought Digital tapes would be easier than the 40 VHS-Cs I did a few months back - wrong! haha)
Not sure about setting chapters automatically; It might be possible in mkvmerge with the original files, I'll have to think about it; but of course those won't be compressed
Uncompressed PCM is not supported in MP4 container by open source muxers, so you might have to stick with AVI or MKV if "copying" audio
Or you can use DVavi helper.zip (needs to install Avisynth + Cedocida DV Codec) then you just drop 60 DVavi clips on make interlace MP4.bat file that encodes interlaced MP4, you get 60 encoded MP4 files in OUTPUT directory.
Defaults are 256000 bitrate for AAC audio and CRF 17 is used with x264 encoder. It can be changed in settings.BAT.
Im going to go with x264 in mkv container.
@poisondeathray solved my issue: I was not encoding as interlaced - BFF which was why videos had aliasing after (but not before) processing.
