C70 HDMI Timecode Delay with external recorder.

[Elwoodjblues1]

Hello, I noticed a minor technical inaccuracy with my EOS C70 and wanted to know if this error occurs with other models in the C series. I connected an Atomos Ninja V to my camera and recorded the HDMI image via the Ninja V in addition to the internal RAW recording. I want to use the Ninja V recordings as notes and for logging the settings. I also have the camera's HUD on the Atomos recording. I synchronised the recordings in Premiere using timecode. I noticed that there is a timecode offset of 1 frame between the internal recording and the Atomos recording. Since I also recorded the camera's HUD, this offset can also be seen when comparing the timecode in the image with the timecode of the file. I thought it might be due to the Atomos and tested the same setup on my  5Dmkv and XF205. I don't have this problem with either of these cameras. Now, out of curiosity, I would like to know whether this error occurs with other models in the C seriesThe timecode of the file can be seen below. The timecode of the recording is shown at the top of the image.

Hi Elwoodjblues1,

The timecode output from our C cameras should match the timecode from the camera itself. There is a setting to double check with an issue like this. Go into the camera menu, go to the System Setup section, select HDMI Scan Mode, and make sure it is not set to PsF (Forced 1080i. When the HDMI scan mode is set to that it does change how the frames are counted in the output and that could potentially cause a desync.

The HDMI Scan Modus was on P not on PsF.
