Had some fun messing around with the 5k build last weekend. I didn't have any motion control system which is to me what really makes a time-lapse more interesting, but I liked the look of things.

One problem I had was pretty serious vertical stripes every time I entered 5x mode. I found that scrolling the shutter-dial - which messes up the frame - repeatedly until the frame returns to normal would sometimes fix this. I also believe that simply recording for 10 seconds or so can also slowly alleviate the problem.

Seems as if Dual-Iso at different bit-depths Just Works.

One thing I'd be very interested in would be even slower frame rates.

Thanks for your hard work RDC, we appreciate it.

I am interested in this build   I have 2 anamorphic setups
one is a Kowa B&H with 50mm 1.2 canon lens and the Redstan collar with
the Rapido 16hva front variable diopter the other is a Kowa 16D with the Redstan
connecting collars and a FD 50 1.4 taking lens  ( for lighter weight)(who am I kidding
they both are heavy  and long)
both setups do vignette heavly on the 5dmk2     so I'm looking for a solution
for this critical shooting  problem
Just stumbled onto this site last night   my interest is glued

Crop mode would probably help you extremely! That as a full frame setup sounds extremely interesting to me though. Anamorphic f/1.2? How much vignetting is there? Do you have any snapshots?

Almost got 50D to compile the crop_rec module , but getting a error
"Will not load on: 50D (fps_override_shutter_blanking) not checked"
?
Of course this stop the crop_rec module from compiling.
I know it has something to do with the video & or shutter hack on 50D as it doesn't have native video support .

Here the added support for 50D , it uses the same values as 5D2 (0x105f & 0x1061) , in fact everything is almost identical to the 5d2  :D
Code: [Select]
    const int blanking_reg_zoom   = (is_50D) ? 0x105F : 0x805F ;     // waza57 for test
    const int blanking_reg_nozoom = (is_50D) ? 0x1061 : 0x8061 ;           // :
    const int blanking_reg = (lv_dispsize == 1) ? blanking_reg_nozoom : blanking_reg_zoom;

shutter_hack movtweaks.c#lines-307
Code: [Select]
#ifdef CONFIG_MOVIE_RECORDING_50D_SHUTTER_HACK

CONFIG_INT("shutter.btn.rec", shutter_btn_rec, 1);

void shutter_btn_rec_do(int rec)
{
    if (shutter_btn_rec == 1)
    {
        if (rec) gui_uilock(UILOCK_SHUTTER);
        else gui_uilock(UILOCK_NONE);
etc. ....
50d video_hack movtweaks.c#lines-466
Code: [Select]
#ifdef FEATURE_MOVIE_RECORDING_50D

static MENU_UPDATE_FUNC(lv_movie_print)
{
    MENU_SET_VALUE(
        lv_movie_select != 2 ? "Disabled" :
        video_mode_resolution == 0 ? "1920x1080, 30fps" :
        video_mode_resolution == 2 ? "640x480, 30fps" : "Invalid"
    );
etc. ....

Is there anyone on the forum left that knows more able this ?
5D2 doesn't have any problem with this so I'm a little lost on how solve this .

Edit: found something that I think could be the issue
50D/EOSM: disabled FRAME_SHUTTER_BLANKING_WRITE  commit f68f196 this different then the 5D2 which has this enabled 
Code: [Select]
**50D.109/consts.h**
-#define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)
+//~ #define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)

Code: [Select]
5D2.212/consts.h
#define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)

I see the EOSM has this also disabled , what would be the reason for 50D to have this disabled ?

Edit:#2
committed 6192a0d
Looks like a1ex disabled this from TL ,
Code: [Select]
/** We can also override shutter on a per-frame basis */
-#define CONFIG_FRAME_SHUTTER_OVERRIDE
+/* really? no other old camera can do this */
+//~ #define CONFIG_FRAME_SHUTTER_OVERRIDE
Not sure if this related but looking like it .
5D2 does not have this , so this seems it could be re-enabled , from what I understand it was disabled because it was a bleeding edge stuff
as no other camera has this & can do this .

Would be nice to find some history notes for this .

I'm thinking now of buying 50d  :D :D

Fixed crop_rec module compiling problem on the 50d
in "platform/50D.109/consts.h" In this line
Code: [Select]
+//~ #define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)

I changed in to this
Code: [Select]
#define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)
Now it compiles but the module error out (module will not initiate startup) after loading .
So something is not letting the crop_rec startup , I guess I have to go over the code again and see what I missed .
I am closer now , just a matter of chasing down the bugs .

@Reddeercity, look, i was playing with 48 fps today trying make some b roll transitions and noticed some strobing or flickering (i don't know how to say it correctly) effect when i was in the room with fluorescent lamps. So it because 1/125 shutter speed. Is there any way to change it in 48 fps mode?
Another question. How do you think, is it real to push fps even more just cutting edges from the right and the left side? It could become 1376x774 (from 1856x774) but with higher fps.

Change your shutter speed to 1/90th - 1/100th of second for 48fps ,
just adjust the shutter speed before you enter into 48p you may have to lower it to 1/40th or lower in 3x3 (FHD) then when you which to crop_rec
it should be right.

I have no plans to increase the fps of reducing frame size for 48fps at this time on the 5D2 .
FYI is close to the edge for 5d2 in 3x3 Hi speed , the 50D will have more frame rate capability ( faster sensor) I can see at least 60 if not 70fps in 3x3
Unless there a problem with 5D2 builds , My time is dedicated now to 50D Crop_Rec & Lossless Compression on 50D & 5D2 .

Understood you, Reddeercity. Wish I could help you, but i'm too old to get into all this... oly can help with testing, checking, filming somthing etc..
Hope you take 50d to a new level :), and even 7D afterwards.
