Hi Steipal,

I am trying to burnt-in Timecode on 15 FPS source file, my output framrate is 25 FPS, after conversion I am getting delayed in burnt-in TC. Please find attached screen shot of the same.

I am using FFAStrans version 0.5.1 and below is my custom command line.

-c:v wmv2 -s 480x270 -r 25 -vf "drawtext=fontfile=/Windows/Fonts/arial.ttf:fontsize=20:x=100:y=30:box=1:boxcolor=black@0.5:fontcolor=white:rate=25/1:timecode='00\:00\:00\:00'" -vb 512k -c:a wmav2 -ab 128k -map 0:0 -map 0:1

If I use normal 25 FPS source, burnt-in TC run properly.

Kindly suggest if I am doing anything wrong.

Thanks
Vijay

Are you using the "A/V Media"-decoder?
Does you command work with a normal ffmpeg.exe command prompt on the same files?

No I am not using A/V Decoder. If I use A/V decoder with built in WMV profile, I am getting error No video or audio found in media.
Yes command is working on FFMPEG.exe normal command prompt but with same Burnt-in TC issue.
Is that mean this is related to FFMPEG?

Then this is clearly an ffmpeg issue. You should always test your custom ffmpeg command in a dos prompt to see if they're ok.
I'm curious; you wrote that you get errors when using the "A/V Media" decoder in conjunction with the built in "Window Media" encoder?

Could you please try this workflow?

Decoders:
"A/V Media"

Filters:
1. "FPS Conversion". Set to 25 FPS and deselect "Keep input frame rate"
2. "Timecode"

Encoders:
"Windows Media"

I have tested it on a 15 fps clip and it should give you correct output.

As you mentioned I have tested, it's working perfectly.
