Really bad artifacting HELP

[Andy Best]

Hello All,

I am a new RED user and I am shooting on 16g CF cards. Lately I have been having issues with artifacting in my footage. I am shooting 3k and never see a problem until I bring it into REDCine and that's when I see glitches, clicks, and pops. Is this a common rookie mistake, if so, what can I do?

Thank you

Andy

It might be useful to post examples or links to footage for a bit of group diagnosis.

I'll try to find a couple screen shots to post.

Try a forum search with the keyword "corrupt"
Maybe that matches your issue

Here are some examples of what is happening with my red footage. These are only about a frame long but I am not sure what is happening.

Thanks in advance for your help.

Typical case of corrupted footage. Most of the time it happens during offloading. If you still have your Cf cards with the material on it you are safe. Otherwise it is a matter of repair in post/skip/double frame. It can show up like this or like half frames or green frames. No real solution, but next time you have to check your CF card reader, The only way to check if there are corrupt frames is transcoding them with a red rocket card, a frame like this will give an error. For the 104 days production I am doing right now, we bought an extra set of 12 16GB cards. We only erase them teh next day when the Post house has downconverted the material for editing and when there are no errors. Adobe Premiere will also give an error on transcoding, but for me, it takes too long to transcode to be a good alternative.

Looks like a bad CF module to me; I had the exact same problem when I go my first RED, then they sent me a new CF module and the problem was gone. Contact the Red bomb squad about it.

Could be your reader is getting hot, try rotating readers to keep them cool. I use 4 on most projects to insure reliability.

Thank you all very much. This is all very valuable information. I appreciate it.

I only have one reader and six cards right now. From the sounds of it I need to get a little more of everything. The reader I am using is a Lexar. Have you heard of it, and is it good? If not, do you recommend a reader?

Thank you again.
