Thank you for this explanation. It seems that Twixtor appears very risky for my shots. Now I must decide what recorder to choose. What compression will be better for 720p with small moving drops of water and many details in move - ProRes or mpeg2(I-frame)?

Thanks for reply. Unfortunately I am totally dependent on EX3 in this project. It's story about birds, nature, with no clear time limits (depends on circumstances, animals, weather etc.). It means that Alexa or Epic will kill the budget.

I'm using Sony EX3 and will do slow motion shots. I need to keep as good quality as possible, because EX3 is only 720p at 60fps. Shots I want to make will be full of dynamic water details, so for that reason I need to get image as good as possible. Besides, I need to make twice as much fps (120fps) of some shots by using Twixtor. Is it good idea to use external recorder 422? I thought about Samurai Athomos (Pro Res) or Nano Flash, but I also read that there is no significant improvement of image quality with this configuration. Due to dynamic water splash and very small drops, certainly there will be visible compression artifacts.The main problem is that I have EX3 only on my list for these slow motion shots. The project is 1080p. What is the way to keep the best quality of 720p with EX3? Does anybody have some experience with EX3 and slow motion with ext.recorder? Best regards

Hi Thank you for reply. Unfortunately I am not able to describe the issue with many details. Cameras were set to non-drop frames (50i). During the shooting I checked TCs after 30 minutes from the synchronization moment. TCs seemed to be OK. Later I got information from editor that TC is out of sync. Biggest difference was around few minutes and it appeared after few hours from the beginning. I don't know if it was slowly increasing or it just jumped in suddenly. I am unable to get more information now. I will be back in some time and will provide more details. Preset-Regen I didn't check... best regards Michal

Hello First time in my life I was forced to shoot video (HDV) with 2 Sony Z1 cameras. I set freerun and synchronized both cameras using remote control. Later turned out that timecodes of these two Z1 are not the same! At the beginning everything was fine. Problem started later. What could be the reason? Internal battery? Did anyone have such problem? Is there any other way to synchronize Z1s and keep them running fine? Thanks, best regards MS

You can choose the system. It can be mpegHD (1440x1080 4:2:0) or DVcam or mpegIMX (4:2:2). XDCam HD at 25MBit/s is similar to HDV but highest quality is at 35MBit/s (VBR). IMX gives interesting look, but it's SD. regards
