![]() In MediaInfo output, the MP4 file container applies "MPEG-4" format.

If MuxMan has no problems with the streams then you can be almost 100% sure that everything is compliant.I have an MP4 file, which I would like to convert into an MPEG4 file. To verify that your streams are really DVD compliant, my method of choice is to demux the MPEG2 file and author the elementary streams with MuxMan. This does not convert a progressive source to interlaced, it just forces interlaced motion estimation and DCT plus the alternate scan order, and it sets the correct field order flag. flags ilme ildct -alternate_scan 1 -top 0 flags ilme ildct -alternate_scan 1 -top 1 To encode in interlaced mode you need to add the following parameters: (Your script provides the possibility to convert to NTSC, and for an NTSC DVD it is not compliant to just have a single MP2 audio track) I would also recommend to use AC3 instead of MP2. Your audio sample rate of 44100 is not DVD compliant, you need to use 48000. Seems awfully low, I remember reading comments where a constant quantizer of 2 was recommended. Well, I am not an ffmpeg specialist, but since nobody has answered for 3 days, I do have some remarks: REM else do a preserve-aspect-ratio scale and pad REM do a straight 16:9 conversion to %width%x%height% "c:\software\mediainfo\mediainfo.exe" -Inform=Video %%AspectRatio/String%% "%~1" > ".\mi.txt" I could easily do it and a lot of other things in avisynth, but I'm not sure how to open an. Are there any ffmpeg filters you would recommend to, say, sharpen and maybe denoise a bit ? ![]() (I will try to burn them tomorrow and see what happens) I have not specified interlacing so is that going to be an issue ? If so, I guess I'll have to find the switches to convert it to TFF interlaced I'm not sure the output files are fully PAL DVD compatible. The ffmpeg settings were "borrowed" from googling (I originally used -target pal-dvd however that over-rode some of the other ffmpeg settings so I had to desist and code the equivalent ffmpeg switches manually after finding out what they were). bat file (code below) produces mpeg2 files. Seeking a bit of advice on an ffmpeg commandline to downscale/upscale/bar-ize/convert a bunch of generally low-res arbitrary-sized old mp4's (free stuff) into mpeg2 files for burning to a PAL DVD, for an elderly relative's DVD player. ![]()
