Burn in TimeCode
Burn in TimeCode
Hi
There is a "burn in TC" in your Filters, but the frames are displayed as 1000/s instead of frame.
Is there a way to burn a tc with frames ?
Best regards
Fabrice

Re: Burn in TimeCode
What fps are your source and can you please post a screenshot of what the tc looks like on video?

Hi Steipal
We are working mainly with 23,98, 24, 25 fps.
The TC I have on the final video is something like 01:23:45:626 instead of 01:23:45:15

Re: Burn in TimeCode
I have found a bug concerning 23.98 fps video and it's fixed for the next release (0.7.3) . Thanks for reporting! I guess you don't have the issue on 24 and 25 fps video?

Re: Burn in TimeCode
That's right. 24fps and 25fps work fine.

Hi There, I'm using V0.9.4.0 and there is still an issue when burning the 23.976 FPS time codeon my clips. it 's not accurate.
Re: Burn in TimeCode
Hi Mahmoud Rady, thank you for using FFAStrans and welcome to the forum!
Can you be a bit more specific? In what way is it not accurate?

Re: Burn in TimeCode
Hi Steinar, would you please check the attached screen shots and let me know if this can be fixed?
on Premiere, the project frame rate is at 23.976 the project starts at 00:00:00:00
at 00:00:41:16 the clip jumps to 00:00:41:19 "2 frames skipped"
at 00:02:05:04 the clip jumps to 00:02:05:07 "2 frames skipped"
the source file is 23.976 and the timecode node is on the default setting.

Re: Burn in TimeCode
This is easily reproduceable for me: Just take a source file that has 23.976 Framerate and send it to a workflow that has AV Decode->Timecode->Encode->Deliver. Voila, right after 00:00:41:16 (Frame number 1000), the next 2 Frames are missing.
The error seems to come from the ShowSMPTE Function within Avisynth.
This avisynth command, which is generated by the ffastrans "Timecode" processer, will bring up the mentioned error at Frame 1000 (= timecode 00:41:16)
Whereas this command will not bring up the error (just the fps Argument is omitted):
I propose to @admin as a solution, in the "Timecode" node, at the "Force FPS" Dropdown, when the value "None" is selected, then omit the "fps" Parameter for the ShowSMPTE function... at least for a short term solution.

Code: Select all
m_clip = ShowSMPTE(m_clip, fps=23.976, offset="00:00:00:00", x=160, y=452, font="arial", size=53, text_color=$ffffff)

a possible Workaround might be connected to what exactly your workflow is doing, will you explain or better upload your workflow please?
My first attempt would be to get rid of any avisynth nodes in the workflow and rebuild their functionality in a custom ffmpeg node...
Another attempt might be to replace the Timecode node by a custom avisynth processor and insert this code
m_clip = ShowSMPTE(m_clip, offset="00:00:00:00", x=160, y=452, font="arial", size=53, text_color=$ffffff)
thanks!
