Hi,

I am using the new surface pro 3 and the app crashes (closes immediately) whenever I try to open MLV file. Doesn't matter if I drag the file or open it via the app.

The logs say:

I started testing the new release from Andy600. Everything seems to be working better mlv-wise. MLV viewer in the camera works 50% of the time. Sometimes it just gives an error and freezes the camera, so I have to remove the battery. My bigger issue though- I cannot open the mlv file on my PC. I can view it in MLV viewer, but MLV2DNG doesn't work (not recognized header "STYL"), and MLVdump doesn't do anything.


How do I get dngs?


Tried MLV_dump with different parameters, it stops working/gives one frame, generally speaking- my file is useless now :(

I just thought of a feature, maybe there is one, but I couldn't locate it.

Framing in zoom mode is troublesome, because it is off sometimes.

How about the camera could take one frame (in crop, with selected resolution, exactly how it is going to look in ML RAW), then display it for a couple of seconds in color and stuff. It would reassure me that the footage is going to be what I had in mind while shooting.

I know I can do that with recording a couple of frames, and then playing them back, but playback is grey, not realtime and I think one fromegrab could also be used as a thumbnail.

What do you think?

I don't have it anymore, but will try to recreate the problem.

It was about 3GB in size. I just used mlv_rec module, manual lens (Helios 44), iso 100. It looked like no problems while recording, but I was using global draw with buffer graph.

I recorded a couple of clips in MLV format today and I can play them in MLV viewer, but colors are wrong, highlights clipped. I cannot convert them in MLV2DNG.

Message "unknown header "styl"". My camera is in polish, can it affect this? Styl instead of "style"? like picture style?

Some clips cause the program to shutdown, some go through when on card, some only copied to HDD. One file works from card, then stops working from hddd.

They go through even without the header.

I tried mlv_dump, but it says that file ends in the middle of the block. I cannot convert them to legacy RAW.

I just got Komputerbay 32GB 1000x from ebay. It goes up to 79MB/s, giving me continuous full frame 16:9, crop 2:35 1920/2000. Perfect for the price.  ;D

I just found this brand on ebay. No mention on the internet. It is cheaper for me than ordering KomputerBay from the USA, but is it worth the risk?

Can you upload a better quality file (prores/tiffs) somewhere? I would like to see if there is any banding happening with all those shades of grey. And better quality shots of the lady too  ;)

This is RAW, I extracted DNG's with RAWanizer and corrected them in AE. I will try to disable focus peaking, but it is disabled while recording.

I know I shouldn't post stupid tests, but I do have a question. I see a little flickering on the left, I like that very much (looks more like film frames with subtle exposure differences). I would like to have control over that, because in well lit scenes, nothing like that happens.

Do we know what causes it? So one could use it as an effect?

Hey guys!

Just joined the 50D club (400$). I have been reading this forum for 2 years now. I have been following the RAW development since the beginning. I read all about it.

My workflow so far: RAWanizer -> AE -> Premiere.

I love the image. I have to get used to image differences, exposing the RAW compared to 550d h.264.

! I think I noticed something interesting !

When importing the DNG's to AE CS6, everything works fine, Camera RAW works perfectly fine.

Then, when I put the footage in 32bit composition (23,976fps), it is usually scaled up/down, due to being 1584xXXX in size. 2:35 aspect ratio. Normal.

Everything was fine so far. Then, I did RAM Preview on full screen and noticed severe aliasing on the edges. I know what causes aliasing (line skipping and shit). Something was odd though. I went back to Camera RAW, and there was almost none aliasing in 100% or 200% preview.

I went back to my composition. When the preview (in normal workspace scenario) is set to "(76%)" or "fit up to 100%" or "fit" it causes aliasing WHICH IS THEN VISIBLE IN FULL SCREEN RAM PREVIEW.

When you switch it to 100% (too big for workspace window) and then go for full screen RAM Preview again THERE IS LESS ALIASING.

So to minimize aliasing in AE CS6, you have to have your preview on 100%. I tested it three times with different footage, same scenario everytime. It seems like Camera RAW preview is almost smooth, then AE goes apeshit with diagonals and sharp edges.

I change composition for 1920, then set 100%, then RAM Preview.

Anybody noticed this?

Peace.

P.S. Still waiting for faster card to try continuous shooting. Then will post some tests (not cats, I will try to edit something of value).
